Evaluation of 17-mm St. Jude Medical Regent prosthetic aortic heart valves by rest and dobutamine stress echocardiography.

Background: The prosthesis used for aortic valve replacement in patients with small aortic root can be too small in relation to body size, thus showing high transvalvular gradients at rest and/or under stress conditions. This study was carried out to evaluate rest and Dobutamine stress echocardiography (DSE) hemodynamic response of 17-mm St. Jude Medical Regent (SJMR-17 mm) in relatively aged patients at mean 24 months follow-up.

Clinical performance of low-profile bioprostheses: results at 10 years.

The purpose of this retrospective study is to evaluate the long-term performance of the Liotta minimally intrusive bioprosthesis (MIB) and to identify its most important risk factors. From January 1980 to March 1982, 73 patients (30 males and 43 females; mean age 45.5 years +/- 11.

[Surgical treatment through embolectomy of embolism of the superior mesenteric artery (author's transl)].

The Authors present four cases of embolism of the superior mesenteric artery treated surgically, with satisfactory results, through embolectomy with Fogarty's catheter. The Authors affirm the necessity of always following this type of intervention, given its simplicity and the high rate of mortality of non treated embolism. Some anatomical and physio-pathological considerations are remembered and diagnostic and surgical promptness are recommended.
